Preparing for the NewGeospatial Metadata

Horizon

Why change our standard?

Politically… responsible member of international geospatial

community

Technically… improved normalization enhanced capabilities interoperability

3

What is the status of the ISO metadata standard? ISO 19115

design only approved by ISO

ISO 19139 implementation draft submitted June 2003

ISO 19103, 19109, 19111 elements defined externally to ISO 19115/10139 e.g measurements and feature/attribute schemas most in draft form

CSDGM remains the US

geospatial metadata standard

4

What’s new with ISO metadata?

1. Content CSDGM similar and new elements domains and conditionality core metadata

2. Format UML / XML Multi-level metadata

5

ISO Metadata: New ContentCSDGM Similar Elements

samemetadata standard name

new terminology and definitionsCSDGM = Originator ISO = Responsible partyw/ role = originator

6

ISO Metadata: New Content

New (non-CSDGM) Elements International elements

Data / Metadata language Extended elements

CSDGM = geographic and temporal extentISO = geographic, temporal, and vertical extent

Lacking elementsISO Topic category – 19 standardized subject categories to facilitate data discovery

7

ISO Metadata: New ContentTopic Categories – select one or moreboundaries oceans transportation economy societyelevationstructureenvironment geoscientific_informationhealth imagery_basemaps_earthcoverinland waters planning_cadastre location utilities_telecommunicationsclimatology_meteorology_atmosphere

8

ISO Metadata: New Content

Domains and Conditionality Fixed domains and code lists in place of free

textResponsible party - role and Topic categories represented as numeric codes

role = originator (006) topic category = transportation (018)

Fewer mandatory elementsCore contains only 7 mandatory elements

More optional elements

9

ISO Core Metadata 22 basic metadata elements be that must be

maintained for a dataset includes mandatory, conditional, and optional

elements all national profiles of ISO must include the

core

conditional elements: CSDGMGeographic location Bounding_Coordinates

- if documenting a data set

- if other than UCS

Metadata language- if not encoded

optional elements: CSDGMOnline resource Online_Linkage &Network_Resource_NameMetadata standard name Metadata_Standard_NameMetadata standard version Metadata_Standard_Vers.

Metadata file identifierfilename for metadata record

Spatial resolution (for vector)e.g. equivalent scale 1:24,000

ISO Metadata: Core Metadata

15

ISO Metadata: New Format

19115 UML Design: entity relationships

16

ISO Metadata: New Format

19115 Data Dictionary: content specifications

17

19139 XML Schema: metadata record format

ISO Metadata: New Format

18

Implications: the good news….XML schema supports consistent and robust implementation via software tools

format and exchange- current implementation via txt, doc, db file, etc- exchange format is txt

internal metadata harvesting and other automated features

ISO Metadata: New Format

19

ISO Metadata: New FormatMulti-level metadataMeta can be created for different levels:

Data Series - wetlands Dataset - Paducah wetlands Feature Type - marsh Feature Instance - Mandy’s Marsh Attribute Type - Salinity Attribute Instance - actual % water salinity

20

Implications: the bad news….Standard can no longer be ‘read’ by most geospatial data developers

greater dependency on tools lack of direct contact with the standard will be

difficult for some metadata creators, analogous to moving from command line to GUI

21

What about my legacy metadata?Crosswalks drafted for:

CSDGM Vers. 2.0 Dublin Core, others

Conversion software in development

sponsored by FGDC ESRI and Intergraph/SMMS development partners

22

How do I prepare?Now….1. Continue metadata creation using CSDGM vers.2 !!!2. Use ISO-poised software

ESRI ArcCatalog Intergraph / SMMS

3. Add Topic Categories as a custom element or theme keywords with ‘ISO 19115’ as keyword thesaurus

4. Monitor FGDC website for news, materials, and training opportunities

23

Soon…5. Participate in FGDC review of crosswalk 6. Participate in INCITS-L1 19139 reviews7. Educate and inform your organization that a migration,

and assistance, is in the future8. Develop a metadata conversion plan using crosswalks

and conversion software9. Adopt ‘CSDGM vers. 3.0’ when finalized

ISO/TC 211Several CSDGM-traditional elements are defined externally to ISO 19115/10139:

ISO 19103

- measurement (distance, angles, units of measure)

ISO 19109- features, attributes, properties

ISO 19111- vertical datum
